Apparatus for marking spherical articles

ABSTRACT

Apparatus for marking spherical articles in which the marking means extends upwardly from beneath and a concave transparent template having a design scribed therein is held above the article. The article is provided with a follower so that when the article is rotated beneath the template, the follower will track and the marking means will function on the bottom of the spherical article.

This invention thus has the same ohjective as my prior US. Pat. No,3.l79.( l3 dated Aprv It). 1 65,

in my said prior patent. the rotatahle hit presses against the uppersurface of the howling hall. as pietured in FIG. 1 of the patent. andthere is little opportunit v to employ a template to guide the rotationof the hall so as to aid the application of the desired design.

in this invention. the spherical article is supported for rotarymo\ement in all directions l as taught in In prior patent or usingsimplified support means shown herein) and the support element isannular so that the marking means can he positioned hcneath the supportto ettcnd upwardly through the annular opening to hear against thespherical article when the same is supported. A stationarv templatesupport means extends aho\e the support element to hold a templateslightl} ahoxe the upper surface of the spherical article. The templateis concave and removahle and its concave undersurface has a designinscrihed therein In this w av. a follower carried hy the sphericalarticle will track through the design forcing the rotation of thearticle to move the undersurfaee of the article against the markingmeans, This causes the undcrsurface to he marked with a copy of thedesign on the template.

As will he c\ident. the template can he made h one expert in serihingdesigns. and anyone can follow it, Also. If an error is made. it is madeon an inexpensive template. and not in the expensive howling hall.

The invention will he more fully understood from the accompanyingdrawings in which:

FIG. 1 is a side elevation. partly in section showing an illustrativedevice constructed in accordance with the invention; and

FIG. 2 is a top plan view of the structure shown in FIG. I.

' Referring more particularly to the drawings. FlG. I shows thestructure in operation serihing a design into the undcrsurface of ahowling hall. The marking means 10 comprises an elevated work tahle llwhich is supported by legs shown at 12 and 13. An annular hall race 14is shown supported at the center of the tahle ll. the tahle ll having ahole l5 formed therein underlying the race l4 so that a drill press orrouter 16 which is carried beneath the tahle I] can push its cutting hit17 upwardlv through the hole 15 and then through the annular opening inthe race 14. The hit 17 is supported by a chuck l8 and the elevation iscontrolled hy the con ventional control mechanism. hcre indicateddiagrammatically hy the control mechanism 20. The drill press or router16 is secured hv screws 19 to the tahle 11 so as to he stahlv positionedbeneath hole IS.

The howling hall 21 rests on the race 14 as pictured. and the hall isfree. except for a template and a spider support therefor to hedescrihed. so that the hall 2| can he rotated as desired h mere handpressure applied to the hall.

A pair of template support arms 22 and 23 are secured to work tahle I]by screws 24 and a template 25 is secured thereto above the ball. as byscrews 26. The template is concave as shown. and its undcrsurface hasdesign 27 inscribed therein.

As can be seen. a follower 28 (a pin or peg which can he spring loaded)is secured to the surface of the hall 21 and this pin is guided into thedesign 27. The follower can he mounted in a hole in the hall or it canhe taped to the hall. At this point. the drill press or router 16 isstarted and control 20 is advanced to start the serihing action.whereupon the hall 21 is hand rotated to move the follower 28 throughthe track of the dcsign. The template 25 is made of transparent plasticto aid this effort, When finished. the drill press or router is turnedoff. and the hit 17 is lowered.

The nature of the spider arms 22 and 23 of the template will he moreeasil seen from Fl(i. 2. and these can he changed to accommodate hallsof different si7e The invention is defined in the claims which follow,

I claim:

1. Marking apparatus for a spherical article comprising. an annularsupport element for rotatahl support ing said spherical article forroitlt} mov ement about the center otthe spherical article in alldirections. marking means extending upwardlv front hcneath said supportelement and extending through the annular opening thereof to hear againssaid spherical article when said spherical article is supported hv saidsupport element. stationarx template support means extending ahovc saidsupport element for holding a template adjacent the upper surface of aspherical article supported h said support element. and a concavetemplate rcmo\- ahlv carried hv said template support means. the concaveundersurface of said template having a design inscrihed therein and afollower means carried h said spherical article to track through thedesign in the template when the spherical article is rotated toconcurrentl v move the undersurface of the spherical article againstsaid marking means to cause the same to mark the undersurface to thespherical article with a copy of the design on said template.

2. Apparatus as recited in claim 1 in which said template istransparent.

3. Apparatus as recited in claim I in which said marking means is arotatable bit for scribing the desired design into the spherical articlewhich is a bowling ball.
